The first sign of a concussion is a headache. It feels like a headache in consequence of a head injury. The level of pain may change: from the mildest to the severest. A headache is usually harsh when it is a concussion. Throbbing ache and pressure simply drive the patients mad. Not just a single field of the head feels that – looks like the symptom covers the entire part of the body. Moreover, the pain may move down to the neck and upper extremities.

The patients with concussion experience problems with thinking and ability to memorize things. It is the brightest notification a person might be having a concussion. Most often, only the memories a person had before the trauma are erased. In other cases, it is vice versa. The person also may lose coordination and balance. Confusion is another typical sign of a concussion. It results in repeating the same things over and over again.

Nausea and experiencing a feeling being sick to the stomach is yet another symptom that you may have with a concussion. While the nausea or sick feeling might be caused primarily from the pain associated with the cause of the concussion, it is also believed that it can be caused by the chemical imbalance within the brain that is often caused with any type of trauma. In many cases, these two symptoms arrive together. The overall feeling of being sick does not leave for a while.
